Requirements for honeycomb aluminum plate

Honeycomb aluminum plate的芯层是典型的多孔结构，连续的多边形孔格呈规则的周期性排列，因而Honeycomb Panel实体部分截面积很小，所以它的密度相对其他夹层材料也很小。由于Honeycomb Panel密度远小于层合板、钢板等普通板材，在体积相同时其质量也是最轻的。aluminum honeycomb panel的质量仅为同体积玻璃钢层合板的9%, same volume steel plate11%, the same volume of aluminum alloy plate23%. This allows aluminum honeycomb panels to save a lot of energy in lightweight applications. The low density and light weight make the honeycomb panel well meet the requirements of aerospace engineering vehicles, trains, high-speed trains, automobiles and ships and other transportation tools for materials.“Lightweight, energy saving and environmental protection”requirements.

(1)Aerospace: Because of the above advantages, honeycomb aluminum plates are widely used in aviation, aerospace, transportation, construction, military and other fields, for the manufacture of rocket fairings, aircraft wings and cargo warehouses, train bulkheads and floors, car skins and doors, building ceilings and curtain walls. The wing, vertical tail, etc., cockpit or cargo compartment floor, door partition, etc. made of honeycomb panels effectively reduce the weight of the aircraft and improve the control sensitivity of the moving parts.

(2)Trains, high-speed trains: bulkheads, control panels, luggage racks, ceiling pads, washing rooms, toilet units, floors, exit doors and four corner doors and other vehicle interior panels can be made of honeycomb panels. In addition, a honeycomb plate material may be used for external components such as a front end, a roof, a fender, and a vehicle body. In addition, the energy absorption and shock absorption characteristics of the honeycomb structure can be used as a protective device, such as installing the honeycomb panel on the front of a high-speed train to protect the personal safety of the conductor in the event of an accident.

我国国家科技支撑计划的重点项目“Introduction, digestion, absorption and innovation of high-speed wheel-rail railway”The main research and production of the subject is high-strength, lightweight, aluminum alloy car body with energy-absorbing structure and vehicle interior decoration materials that meet the performance requirements of durability, fire prevention, vibration and noise reduction, and environmental protection. The aluminum honeycomb panel is one of the plates that can meet the above requirements.

(3)Automobile: The main way to save energy and resources and reduce fuel consumption is to realize the lightness of vehicles, that is, the lightness of vehicle materials. According to the report of the World Aluminum Association: every reduction in car weight1%Can save fuel0.6%一0.8%. The application of lightweight sandwich structure materials, especially honeycomb sandwich structure materials, will make automobiles lighter in weight, better in impact resistance, and better in safety and comfort. It is one of the development directions of automobile industry materials.

夹层结构材料大部分用在车身外蒙皮、车架结构、车身结构、保险杠、车门、座椅等处。如用玻璃纤维增强热塑性面板和聚丙烯蜂窝芯复合Honeycomb Panel制造轿车的行李后搁板、承重地板等，可以获得非常大的损伤容限。用环氧系粘结剂将纸蜂窝芯与上下两层防锈钢板复合形成Honeycomb Panel用作汽车地板和车顶衬里，具有较好的吸声性能。美国GEThe company uses a new composite material consisting of martensitic steel, a reaction injection molded fiber-reinforced polyurethane layer and a polyethylene honeycomb layer to make car bumpers. This bumper is lighter than the same product made of steel.9kg, can satisfy5km/hThe impact experiment. Many concept cars in Japan also use aluminum honeycomb panels to make car floors, which reduces the weight of the car body and increases the rigidity of the car body.

(4)Ships: with traditional materials(Such as wood, metal, fiber reinforced composite plastic)Compared with the manufactured structural parts and non-structural parts, the corresponding components made of honeycomb sandwich material are respectively reduced.50%和75%The quality. It can be used to produce bulkheads and hulls for fast ferries, as well as lightweight masts for racing boats. That is, the weight of the ship is reduced, and the stability and flexibility of the ship are improved. Domestic also began to apply aluminum honeycomb panels on ships. In order to reduce the weight of the hull, simplify the structure and improve the efficiency, the lightness of the internal equipment of the hull has been paid more and more attention in foreign countries, and the aluminum honeycomb composite panels have been adopted for the inner wall panels, ceilings and door panels. This new technology changes the technical performance of the parts, prolongs the service life, and reduces the maintenance and repair work. At the same time, it gives people a sense of comfort and improves the aesthetics of the cabin.
